To .all whom'it may concern:

Be it known that I, ThonvALn HANSEN, of Everett, in the county of Middlesex and State of Massachusetts, a citizen of the United States,A have invented a new and useful Improvement in Machines for Making Vul canizedfFiber Tubes,` of which the following is a specification.

The machine embodying my invention is intended primarily 'to make vulcanized fiber tubes foruse yin I0 making roving cans, and while machines have heretofore existed in which a tube was formed by winding a sufficient number of layers oi la web of paper upon a mandrel, and attaching them together during the windoperation by paste or otherwise, my machine I F blifv t`o` bean improvement uponall such, because notwithstanding the necessary size and weight of" the parts, it is so constructed that it may be easily handled, and tubes as large assay 14 in diameter may be made and removed. from the mandrel Without being cutv` therefrom as has been the case in every machine for making vulcanized ber-of which 1 have knowledge.

M yinvention will be understood by reference to the drawings, in which v Figure 1 is a side elevation, partly in section, of a machine embodying my invention; Fig. 2 is an eleva- .Y tioii of the opposite side thereof. Fig. 3 is a rear view,4

and Fig. 4 is an enlarged detail showing the stop mechanism. Fig. 5 is a longitudinal section of vthe mandrel, and Fig. 6`is a cross sectionfm line 6 6 of Fig. 5. The machine is mounted on afsuitable framecomprising base beams A, resting upon suitable blocks a, uprights A1 and tie beams A2. Within this frame is located a tank B of suitable width, adapted to contain suluric'acid or other liquid with which the paper is to be treated. The paper itself is in a roll C, mounted in suitable bearings C" sliding in ways on a blockC?, the location of the bearings being controlled by adjusting screws c passing through blocks c1 mounted on the block Cleach adjusting screw having a collar ci to prevent 40 it from moving lengthwise in 'its block cl. The web of paper passes from this'roll C up over a steam heated zoll D mounted in bearings D carried by the tie beams A2, d being a steam inlet, and d1 a steam outlet or waste.

AV frame B1, slightly wider than the `web of paper,

hinged between the uprights Al and carrying guide `rolls b 'for the paper, is constructed to lie normally Within the tank B and to afford meansior holding the paper web down within the liquid in the tank, this construction being indicated inFig. l, where the web .50 of'paper isl shown passing under the rolls b and up out r'ornhe tank.' A handle b1 is attached to the frame Bl for the purpose of lifting the frame out from the tank and replacingit again when it is necessary to renew the paper.

The course of the paper after it leaves the tank is between Scrapers b2, b3, located'just outside the tank and adapted to engage the surface of the paper so as to free it from any unnecessary amount of acid, these Scrapers being mounted upon the tie'beams A2. The paper then passes upward over a steam heated roller E and around the lmandrel F upon which it is wound, being compressed against it by the heated roller E.

Rotation is given to the mandrelF by means of the gear`G mounted upon a sleeve f which projects from the head f1 of the mandrel F. rlhis gear Gr meshes 65 with a pinion Grl mounted on a shaft Gr2 running in bearings in the upright G3 and block G4 supported in the frame, the sha-ft also carrying fast land loose pulleys G5, G6. I

The steam heated roll E runs by frictional engagement with the surface of the mandrel or whatever is lwrapped about it, and for this purpose it is mounted in bearings on the ends of a yoke lever El, the forks of v'hich are iulcrumed in uprights E?, oneat each side of themachine.

The end of the single arm e of the lever is pivoted to a block e1 adjustably mounted on the rod e2, theA lower end of which is connected to a rocker arm e3 on the en d of a shaft e* carried in the upright e5, moun ted on the tie beam A2 and in one of the uprights E2. 80 The shaft c4 has also mounted on it a handle e which serves not only to lift the roll E offirom the mandrel F by means of the rod e2 and lever e. but also serves to temporarily remove the bearings from one end of themandrel and leave it supported by its other end. For this purpose the bearing in question (see Fig. 2) comprises a level- '.E, one end of which is suitably shaped to receive the sleeve f 2 projecting from the head f3 oithe mandrel. This bearing F1 is supported by means of an -arm F2 pivoted thereto and carrying a 90 -riction roll f 12 which while the bearing is moving runs on ablock f1J mounted on the frame thus taking some ofthe weight of the bearing.

F3 is a lateral extension to and rigid with the arm F2 to connect it with a slide arm F?. The rear end oi 95 the bearing lever lm is .forked as at F5. Upon thelshaft e4 there is also provided a rocker arm or segment e7 -carryin'g a pin es which is adapted to engage a fork F5. A pin F is located on the slide arm F to engage an arm e9 also carried by the shaft e4. Thus the turn- 100 ing of the crank handle e in the first place lifts the roll E, in the second place pushes the arm F2 to the loft (see Fig. 2) so as to release the bearing lever F, and also positively moves this lever around its :tub crum so that it leaves` the end of the mandrel iree 192i or the withdrawal of the tube. A pin f1'2 limits the movement oi the lever F8 in ohe direction. l. have provided my machine also with al stop mechanism whereby when a suicient number of layers of web l1ave been wound upon the mandrel F, the machiney will stop automatically. For this purpose l there is a racl; H sliding in bearings upon the side of 5 the frame of the machine and provided with a stop h adjust-ably located thereon. The extension f of the mandrel F carries a cani h1 which engages a lever h.` ulcrumed at ha upon the plate H bol ted to studs projecting from the uprightl'z. Upon the end of the l lever h2 is mounted a pawl h4, the proportion and arrangement of these parts being such that with every revolution of the mandrel, and consequently every engagement ofthe cam h with thev lever h2, the rack H is raised one tooth by the pawl h4. A ,holding pawll h5 is provided to engage the teeth of the rack to prev vent the rack from slipping'back when it is being set by the lever h2.' Both pawls are spring controlled.-

Tofdisenga'ge the pawls and allow the rack to fall, l provide a second lever j adapted to engage both pawls -.20 h4, hpand -cause them to release the rack. In order that this maybe done by hand l connect the tail -piece of this lever j by means of a connecting rod jl with'a lever fulcrurned at j3 to a bracket on the "upri'ght E'which lever isA operated by a pull rod j44 'v mounted in bearings j?, supported on the machine, a handle 7'0" located at the operating end ofthe machine enablingthe operator to throw lthese pawls at pleasure..-

Themaehine is stopped shipping the belt fromthe v fast pulley tolthe loosepnlley. For this purpose a. SO'belt shipper is provided, shown atr K, attached to a Sliding rrod which" ses 4n mmiiy in. the position -i shown in Fig. 3, being held in that positionfby` a spring c.

Sthat byy pulling. the handle leverlK towards `the vleft.against the. force oi the spring' k, the'belt shipper will carry the belt from theloose pulley G tothe fast 470 pulley Gand in order't'o maintain-it in. that position- *l for/a ppoper length of 'time to allow the machine to make a tuheya latch. g ifi-providedwith a si'iit'able' shoulder which engages an" arm. K3 projectingfrom the belt shipper rod K2, y v- In order: to stop the 4machine automaticallythe stop v 'h` on the rack H having been adjusted at a proper-position'on theA rack according to the .desired -time o stopping, when therack has been lifted a proper dis 4 tance, lifts the latch 'gand causes its disengagement from the arm lK3 on the belt shipper rod, vthus allowing the spring loto tl'irow the-.belt shipper rod and carry the belt from the fastl to the loose p'ulley In order that this may be done by hand a long lever c4 is'provided pivoted at h5, and controlled'by the spring k6,

- this leverengagiing the latch and causing it to release theshippingro'd like manner.

After the machine has been stopped automatically y as described, if it is desiredto trim up the edges ofthe tube which has been wound, this may be accomplished 6 0 means of. knives L mountedupon-a4 rockerrod'vl, suitably supported at the end'of thel machine, and l providedV lilith a handle l1'. By turning this handle 4 theseknives can be brought against the tube and veach edge out, andif desired, apiece cutoff from one end.

6.5 Thishavingbeen accomplished and it being'desired to.

remove the tube from the mandrel, the handle en is moved so that the roll E is lifted and at the same time the bearing I"1 of one end of the mandrel is dropped so that the mandrel is supported entirely fromthe power end of the machine. ln order to get the tube off the mandrel, however, I prefer to make the mandrel expansible in character, and have shown one means for doing this in Figs. 5 and (5. The main part F7 ol the mandrel is made preferably of steel, for example, having a certain amount or' elasticity, and is attached to the head f1 by means of bolts f4. Through it Aruns a shaft f which extends outward through a loose, heady f3 at the opposite end of the-mandrel so that the mandrel Aitself is centered upon this shaft. lhe end f l oi this shaft is squared so as to receive a wrench.

The mandrel is not entirely cylindrical there. being a gap between its two ends'which gap is provided, as' shown in Fig. 6, with inwardly projecting edges, leaving a wedge-likev cavity' between them, and in this cavity sets a wedgef7 ruiming the length of the cylinder which is thrownup to Vform a closure and complete the cylinderV by means of links f 8 connected to eccentric straps f carriedoneccentrics fl keyed to the shaft f 5. Turning the shaft'f therefore withdraws the wedge f 7 and allows the mandrel to collapse. The loose head f 3 being removed the tube can then be slipped off from the mandrel without trouble.

-ln operation the web of paper being supplied at C and its end carried over the stationary surface D and through the tank B of sulfuric acid under the rolls bl is passed between the Scrapers b2, b3, and up over the roll E so thatits end is caught between this roll and theiandrel F. Steambeing supplied to D and E the mandrel .F is rotated so that the web is wound upon it whilestill Wet and hot, and successive layers are compressed against each other by means of the roll- E. During the' rotation of 1 ;hemandrell F' the rack H is raised Lstep by step until the stop h coming in Contact .with the latch q causes itl to! release the belt shipper 'which had previously been. set to start up the machine. Thus the machine is caused to stop vand the portion of the web mountedl upon the mandrel is eut'from the re'st of the web. :The mandrel is then turned one or more revolutions to give a final compression to the lay ers, and during these hnal 'revolutions the handle l is turned to cause the knives L to trim and cut the com-V pressed tube which has then been formed in thc desired manner according tothe location of these knives.

The machine beingv again stoppedgthis time by hand through the action of. the 'hand lever lc, the next act is the releasing of the free end f 3 of the mandrel in order thatthetube may be slippedoff, and for-thispur- I pose the handle e6 is pushed downward so as to remove the support-'F2 fromunder the free end of the lever F1,

and a further movement of the hankdle causes the en-4 gagement of the pin e? with theiork F5 so that the lever F1 is positively moved away fromits position as a bearing floor for that end ofthe mandrel. This same action causes the roll E 1tobe lifted off from themarn' 'drel7 the handle'e -beinggmovd solar around thatthe rocker arm e3 will come in toa substantial line Wliththe connecting rod e2, and so hold theroll E in its elevated moved. and the tubevis slipped off from the end, after `Weinfest acid slayhbeyashed sur from it and if. win

` position. The free head f 3 of the mandrel is .then ref' be found when dry to be composed oi what is ordinarily known as vulcanized fiber, having a tenacious, homogeneous character, and Without any apparent Vlayers of the web superimposed upon each other.
